Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Really dont have any description for anything.
This was made in a few seconds and i noticed there isnt any good builds for Olaf.
The build works great for me and after u get the Bloodthirster and combine that with Vicious Strikes ur nearly immortal.
The choise beetween Starks Fervor and Malady.. I personally played Malady first but changed to Starks Fervor after trying it out. Depends on how the game goes.
I get the Frozen Mallet, Warmog's Armor and Sunfire Cape beacouse of his passive. You haft to use it to it's fullest.
HOW I PLAY OLAF
If u face some ranged enemies dont be scared. You can easily harrass people with Undertow. Sometimes when i face some not so good people i try to get my Undertow ability to level 5 as fast as possible just to harrass even more. But if they push u back it's better to go for the Vicious Strikes ability and kill of units when they are close to ur tower. If the enemie have low health and is standing by his/her tower, u can run up and use the Undertow ability to damage them without their tower damaging you.
Later that game when i've gotten the Frozen Mallet. I go for ganks, mid is helpfull. I mostly play with my friends so it's easy to tell them when to gank. If u want to be certain that u'll get the kill just save ur Reckless Swing until they are low on health..
Some Champions i like to lane with would be: Soraka, she can heal me up and also constantly provide me with mana.
And ofcourse Sion, dont you all love his stun? :D
Hope this helps
